Quite true and when in qso I do try to center the desired signal in the passband and when the qrm is bad the K3 absolutely shines! It's so much fun to turn that knob, narrow the passband to a sliver of spectrum and see and hear every other signal disappear.
Still, it would be nice to be able to at least see the full 6 KHz. Sort of like a mini-panadaptor. Perhaps it's time to order and LP-Pan! -----Original Message----- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Friday, September 19, 2008 2:36 PM To: Dave Quick - KØEKL Cc: [email protected] Subject: Re: [Elecraft] K3 PSK31 with Digipan Dave, OTOH, best results with AFSK is to use a narrow receive filter. It keeps strong undesired signals out of the passband. Strong undesired signals in the passband cause a reduction of receiver gain because the AGC reacts to them. Sure, the computer can handle and display them, but if the receiver gain is reduced because of a strong signal that just came on, your chances of maintaining solid print is reduced. Do as you choose, but I prefer to tune my data mode signals just like any other - with the VFO knob, and use a narrow filter to get rid of the 'other trash' on the band. 73, Don W3FPR Dave Quick - KØEKL wrote: > I'd like to be able to transmit in Data-A mode through my 6 Khz AM filter. > Being able to see ~6 Khz of spectrum in the waterfall window would be great. > > -Dave Quick KØEKL > > > > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Joe Subich, > W4TV > Sent: Friday, September 19, 2008 11:55 AM > To: 'zibs'; [email protected] > Subject: RE: [Elecraft] K3 PSK31 with Digipan > > > >> But in Data A mode, one can expand the receive width out to >> 4 kHz using the 2.7 kHz filter.
